  • Publication number: 20060284568
    Abstract: A power supply system for powering backlight lamps in a flat panel display with reduced dimensions and increased power efficiency. The power supply system includes a converter circuit for converting an alternating current (AC) signal from an AC power source to a high direct current (DC) signal, and a high voltage (HV) inverter system that includes a power stage circuit, a transformer circuit, and a current balance circuit. The HV inverter system is coupled to the converter circuit and specifically configured to convert the high DC signal into an AC output signal to power the backlight lamps.

  • Publication number: 20060281488
    Abstract: The present invention discloses a dual-band RF transceiver. The transceiver comprises a first module, used as the RF front-end of the dual-band transceiver and used for receiving and transmitting a first RF signal and a second RF signal; a second module, electrically connected to the first module, used as the IF IQ modulator/demodulator of the dual-band RF transceiver; a third module, electrically connected to the first and the second modules, used as the tripe-band phase-locked frequency synthesizer of the dual-band RF transceiver and used for providing a first local oscillating signal and a second local oscillating signal to the first module, and a third local oscillating signal to the second module. The dual-band RF transceiver according to the present invention realizes the dual-band triple-mode operation of IEEE802.11 a/b/g by a single dual-band RF module, and therefore the circuit size, power dissipation, component count, and cost can be dramatically reduced.

  • Publication number: 20060279362
    Abstract: The present invention discloses a gain amplifier, capable of concurrently operating at three different frequency bands. The gain amplifier comprises an amplification stage for amplifying a signal applied to an input of the amplifier and a triple-band resonance load connected between a DC bias voltage and a DC bias input of the amplification stage. The triple-band resonance load uses a set of reactive elements to provide match in a first frequency band, a second frequency band and in a third frequency band, such as at 2.4 GHz, 5.8 GHz and 9.0 GHz. According to the gain amplifier of the present invention, it can effectively provide triple-band signal amplification and in-band interference suppression for various multi-standard coexist communication systems.
